Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed October 1, 1904:- Serial No. 226,867.

To (LU. whom, it may concern:

Be it known that'l, OLE A. ANDERSON, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Vises, of which the following is a specification.

My invention relates to improvements in cabinet-Vises; and its objects are, first, to provide a cabinet-vise that may be easily and readily adjusted as to the width of the opening of the jaw and, second, to provide a speedy and reliable means of adjusting the jaw vertically. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a bottom plan of the vise. Fig. 2 is a side elevation of the same. Fig. 3 is a face elevation of the adjustable jaw, showing the distribution of the several guides. Fig. 4: is an end view of the screw, showing the po sition of the pawl and trip; and Fig. 5 shows a direct-acting pawl.

Similar letters refer to similar parts throughout the several views.

A in Fig. 2 represents a portion of the bench-top to which the supporting-plate Bof the vise is secured by means of bolts Z) through the holes 6 and which forms the permanent jaw of the vise. The adjustable jaw G is supported by guides D and D, the guides D being rounded at (Z, where it passes through the jaw. so that it may be made to revolve freely by the use of the lever G, and is made substantiali y square the balance of the length and passes through a corresponding aperture longitudinal of the screw E, so that it may be easily moved longitudinally therein and will cause the screw to revolve when it is revolved, as hereinbefore suggested, and move lengthwise through the nut F. The upper surface of the guide D is serrated, as at h,

and a pawl H is pivoted to the end of the screw E in position so that the spring H or other suitable spring will force it down to engage the serrations /t, as indicated in Fig. 2, so that when the guideD is turned the screw E will turn with it and will, through the engagement of the pawl with the serrations, as hereinbefore stated, draw the adjustable jaw 0 toward the permanent jaw or bench-top A, and when it is desired to quickly increase or decrease the opening between the jaws the screw is turned backward until the foot f of longitudinally in the nut, and when to the proper position a slight turn of the screw ahead will disengage the trip from the incline and allow the pawl to again engage the serration in the guide .and render the vise again effective.

The guides D are permanently secured in the jaw C and are arranged to be held in alinement in and to move freely longitudinally through the bearings cl to hold the jaw C permanently parallel with the edge of the benchtop A.

In Fig. 51 have shown the pawl Hprojecting back of the pivot-point h in position to be engaged by the projecting portion 6 of the plate B to form the trip for disengaging the pawl from the serration it, and it is obvious that other available forms of pawl and trip may be used.

To render the adjustable jaw vertically adjustable, I place a thin metal plate C upon the inner face of the jaw O and hold it to place by dovetailed guides 0, made integral with or securely attached to the jaw C, as indicated in Fig. 3, and place bearings I and 0 to support the screw J, which engages the nut J, said nut being integral with the plate 0 to raise and lower the plate by turning the screw J.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

In a quick-acting vise, a supporting-plate and nut, a stationary and a movable jaw, a hollow screw engaging the nut, a guide revolubly connected to the movable jaw and passing through the screw, serrations on one side of the guide, a pawl pivoted to the screw and engaging the serrations, an actuating-spring and a trip, and a lever attached to the pawl and extending down at right angles therewith to engage the trip, as described.
